In the thesis, internal WWAN (Wireless Wide Area Network) and LTE (Long Term Evolution) antennas having eight-band operation capability and suitable to be embedded in the portable devices are proposed. First, a modified structure of monopole antenna is used to produce two resonance frequencies at 0.821 GHz and 1.762 GHz, which are able to contain tri-band GSM850/GSM900/DCS1800 operation. Then, the half-wavelength parasitic path adjacent to the monopole antenna results resonance frequency at 2.352 GHz, which coverage PCS1900/UMTS2100/LTE2300/LTE2500 operation. Finally, by using a plate (High 3mm) and printed circuit board (PCB) combination of antenna, it improves impedance bandwidth and covers the LTE700 band. The monopole antenna of a simple structure and being easy to construct with low cost, is presented. It can cover eight bands, including three LTE bands of LTE/700/2300/2500 and five WWAN bands of GSM850/900/DCS1800/PCS1900/UMTS operation, and occupy a compact volume of 60 × 17 × 3 mm3. Detailed antenna designs and experimental results are presented and discussed.
